For a better understanding of the invention a reference may be 0 drawing in which:

Figure 4 is a perspective view of. a' roofing section showing a starting layer.

Referring specifically to the drawing in which like numerals are used to of wooden planks applied to cover joists 2 which upon the wall joist 3 of the build-" 45 are mounted ing frame. course of sur body portion Numeral 4 designates a starting facing units eachof which have a 5 provided with a portion 6 project-- ing at an angle therefrom. This angular por- 50 tion may be of any conformation but is typified in the drawing as being formed with a circular interior surface 1 and an exterior circular surface 8, this a project over 5 vide a finishe ngular projection being adapted to the edge of the roof deck and prodedge 9 for the cave and simulates a roofing .covering of much greater thickness than the actual thickness thereof.

The starting course may comprise a single layer of roofing units or a double layer. It a single layer is employed,- anundersurfacing of 5 saturated felt or waterproofing covering I0 is necessary in order to protect beneath the joint seams between the .roofing units. The felt covering may be applied to underlie the starting course, or it may be applied to underlie the other 10 roofing courses 8 also.

If the starting course comprises a double layer of roofing units, the waterproof covering this optional and may or may not be employed, as desired. If a double layer of roofing units are employed for the starting course they are arranged in 011 set relation to break joints the sameas would be done in laying'units of conventional design. A 'double layer, hereinafter described, has

prising complementary units having a body portion 4 and an angular projection 5', the latterl of which is slightly smaller in diameter so that the angular projections 5' of the complementary course may nest in the angular projections 6 of the main layer. The interior diameter of the complementary unit will be substantially of the same contour as the exterior circumference of the angular portion of the main unit. Shingles of the same size and conformation which are employed for the starting course may also be employed for the finishing course adjacent the ridge.

In the finishing course the angular projections are positioned upwardly and the ridge member II is contoured with terminal edges l2 in order to cooperate with the angular portions of the surfacing elements, and provide a watershed when the said elements are associated in spaced relation. The ridge strip may be suitably mounted upon ridge pole l3 by nails l4 and if the nails alone are not suflicient to hold the ridge strip in position further anchoring means in the form of guide rods l5 may be employed, one end being attached to some portion of the ridge strip and the other end being attached to the element.

To prevent birds from having access to the building, a screen l6 may be advantageously employed to cover the ventilating space between the surfacing units and the ridge strip. This screening in the present instance is typified by stripjwhich is fitted between the ridge strip and having its edges projected to engage with the top surface of the roofing. A screening I 1 may 65.

While I have illustrated and described one pre- I ferred embodiment of the invention it will-be understood that there may be various changes in details of the construction comprising a sheet having a body portion provided with a marginal edge projecting at an anvide a simulated thickness greater than the actual thickness of the body portion, said .unit adapted to be laid with the projecting marginal edge disposed toward or away from the surface to be covered, and a separate complementary sheet of similar construction adapted to nest with the first mentioned sheet.

2. A ventilated roof structure comprising a roof space provided adjacent the cave and ridge, and a roof covering applied to the deck having a terminal portion projecting at an angle from the base portion thereof to cooperate with some portion of the roof to provide a watershed ventilating space at the eave and a watershed ventilating space at the ridge.

the base portion thereof to cooperate with some portion of the roof to-provide a watershed ventilating space through the roof and having another portion projecting at an angle to overhang the eave space.

- 4. A ventilated roof structure comprising a roof deck having a space therethrough provided ad-v jacent the eave, and a roof covering applied to the deck having a terminal portion projecting at an angle fromthe base portion thereof to cooperate with the space adjacent the eave to provide a watershed ventilating space through the roof.

5. A ventilated roof structure comprising a roof deck having a space provided adjacent the eave and the ridge, and a'roof covering applied to the deck having a terminal portion projecting at an angle from the base portion thereof to cooperate 4 with the space adjacent the eave and another angular terminal portion cooperating with the space adjacent the ridge to provide a watershed ventilating passage.

6. In a building structure, a ventilated ridge,

a ridge member composed of asbestos cement materials curved. so as to cover the ventilating space, asbestos-cement materials applied to the roof adjacent to the ventilating space and curved outward from the roofing in under the cover members so as to form a circuitous passage for the entry of air into the building, an eave vent and asbestos cement shingles applied to the roof adjacent to and overhanging the eave vent.
